Header for imposing frictional force on terminal posts

Abstract

A header for self-securement to terminal posts extending from a printed circuit board (PCB) includes a member selectively movable into frictional engagement with terminal posts to provide for an increase in retention force as between the header and PCB independently of the force established for insertion of the header upon the terminal posts.

What is claimed is: 
     
       1. A header for receiving an array of terminal posts and effecting self-securement thereto comprising: an insulative housing comprising: a body portion including thereon a plurality of post receiving channels being configured to removably receive said posts, said body portion adapted for receipt of an electrical connector; and   a movable housing member secured to said body portion for providing retentive engagement of said electrical connector and for selective movement into direct frictional engagement with at least one of the posts received by said header whereby said header exhibits a withdrawal force from such self-securement to said posts in excess of force required for insertion of said posts therein.     
     
     
       2. The header claimed in claim 1 wherein said post receiving channels are provided in respectively differently configured first and second types, such movable housing member being supported on said body portion for selective movement into interference registry with such second type channel. 
     
     
       3. The header claimed in claim 2 wherein such first type channel is fully perimetrically bounded by said body portion and wherein said second type channel is bounded jointly by said body portion and said movable housing member upon such movement thereof into interference registry with said second type channel. 
     
     
       4. The header claimed in claim 3 wherein said body portion is an upstanding element defining vertical partially circumscribing boundary for said second type channel, said movable housing member defining further vertical partially circumscribing boundary for said second type channel upon such movement thereof into interference registry with said second type channel. 
     
     
       5. The header claimed in claim 4 wherein said movable housing member is supported for rotative movement on said body portion. 
     
     
       6. The header claimed in claim 1 wherein said body portion defines a recess for receipt of a said connector for further receipt of said posts. 
     
     
       7. The header claimed in claim 6 wherein said movable housing member defines surface for retaining said connector in said housing upon such movement of said movable housing member into frictional engagement with such post. 
     
     
       8. The header claimed in claim 7 wherein said movable housing member defines further surface for ejecting said connector from said housing upon movement of said movable housing member out of such frictional engagement with such post. 
     
     
       9. The header claimed in claim 1 wherein a first set of channels of said body portion boundingly receives posts of said array and at least one channel of said body portion non-frictionally receives at least one post of said array.
